Reinforced and toughened geopolymer and preparation method thereof
The invention belongs to the technical field of geopolymers. The invention provides a reinforced and toughened geopolymer. The reinforced and toughened geopolymer is prepared from the following raw materials in parts by mass: 30-40 parts of zinc oxide rotary kiln tailings; 15-25 parts of an aluminum-silicon raw material; 4-8 parts of an exciting agent; 2 to 4 parts of potassium titanate whisker; 1-3 parts of sodium tripolyphosphate; 2-4 parts of fibers; 1-3 parts of a silane coupling agent; and 15-20 parts of water. The invention also provides a preparation method of the reinforced and toughened geopolymer. The geopolymer disclosed by the invention has excellent early compressive strength and early breaking strength, and the later strength is remarkably improved; the cement mortar has good toughness and volume stability, strong dry shrinkage resistance, freezing resistance and cracking resistance; the coating has the advantages of simple preparation process, good durability, long service life, good curing effect on toxic heavy metal ions and good corrosion resistance.
本发明属于地聚物技术领域。本发明提供了一种增强增韧地聚物，由包含如下质量份的原料制备得到：氧化锌回转窑尾渣30～40份；铝硅质原料15～25份；激发剂4～8份；钛酸钾晶须2～4份；三聚磷酸钠1～3份；纤维2～4份；硅烷偶联剂1～3份；水15～20份。本发明还提供了一种增强增韧地聚物的制备方法。本发明的地聚物具有优异的早期抗压强度和早期抗折强度，并且后期强度显著提升；具有良好的韧性和体积稳定性，抗干缩性强，抗冻性和抗开裂能力强；耐久性好，使用寿命长，对有毒重金属离子的固化效果好，具有良好的耐侵蚀性。
